Identifying Lines of Symmetry
Young scholars calculate the lines of symmetry using polygons. In this geometry lesson, students graph, compare and estimate using collected data. They identify different attributes to the polygons based on their sides.
Curated OER
Studying Special Segments in Triangles
Learners investigate special segments in triangles. In this geometry instructional activity, students graph, compare, estimate and predict findings based on their data. They differentiate between similarity and congruence of triangles.
Curated OER
Mathematics in Robotics
Young scholars build and create using math. In this geometry instructional activity, students differentiate between congruent and similarity as they observe polygons. They create robots with different functions using properties of geometry.
Curated OER
La Toteca- A Tropical Paradise
Students collect data on the time of the ferry. In this algebra lesson, students use the data to predict a ferry schedule. They also compute the depth where oxygen would be needed when diving.
Curated OER
Fun With Fractals
Students use fractals to analyze nature. In this geometry instructional activity, students work in groups using technology and math to communicate. They identify where in the real world fractal can be seen.
Curated OER
Exploring Centers of Triangles
Students explore properties of triangles using angle bisectors, incenters, circles, midpoints, and altitudes. They use Geometer's Sketchpad in order to create triangles and their properties.
